Description

本発明は、従来の天然水硬性石灰と比較した場合に、より良好な注入特性を提供するナノ水硬性石灰を含むレディインジェクション材料の製造方法に関する。 The present invention relates to a method for producing a ready-injection material containing nano-hydraulic lime, which provides better injection properties when compared to conventional natural hydraulic lime.

注入法（グラウチング）は、歴史的建造物の修復で頻繁に使用される方法のうちの１つである。注入が適用されている間、使用される注入材料は、歴史的建造物内に存在する固有の材料に適合し、かつ修復される亀裂に浸透できるものとする。注入材料の注入性能を高めるためには、組成物中に存在する材料の粒子寸法を考慮に入れる必要がある。ナノサイズの石灰を使用することにより製造された注入材料により、はるかに薄い亀裂の修復が容易に実現される。現在の技術によって、歴史的建造物を補強するために必要とされる浸透、体積固定及び抵抗値を提供することは困難である。 The injection method (grouting) is one of the methods frequently used in the restoration of historic buildings. While the injection is applied, the injection material used shall be compatible with the unique materials present in the historic building and shall be able to penetrate the cracks to be repaired. In order to improve the injection performance of the injection material, it is necessary to take into account the particle size of the material present in the composition. Injectable materials made by using nano-sized lime facilitate the repair of much thinner cracks. Current technology makes it difficult to provide the penetration, volumetric fixation and resistance values needed to reinforce historic buildings.

本発明により、強度が高く、注入に好適である石灰を製造することを目的とする。本技術の既知の状態では、ナノサイズの石灰の製造及び天然の水硬性石灰の製造に関連する別の研究が存在する。主題特許出願では、単一の原料を使用することにより、天然の水硬性石灰をナノサイズで開発している。 An object of the present invention is to produce lime, which has high strength and is suitable for injection. In the known state of the art, there are other studies related to the production of nano-sized lime and the production of natural hydraulic lime. The subject patent application develops natural hydraulic lime in nano size by using a single raw material.

本発明の構造的及び特徴的特性及びすべての利点は、以下に記載の詳細な説明により、より明確な方法で理解され、評価は、以下に記載の詳細な説明を考慮することによって行われるものとする。 The structural and characteristic properties and all advantages of the present invention are understood in a clearer manner by the detailed description described below, and the evaluation is made by taking into account the detailed description described below. And.

この詳細な説明では、ナノ水硬性石灰を含むレディインジェクション材料の主題の製造方法は、任意の限定的な効果を形成することなく、主題をより理解しやすくするためにのみに実施例を参照して説明する。 In this detailed description, the method of making a subject of ready-injection material containing nano-hydraulic lime refers to examples only to make the subject more understandable without forming any limiting effect. I will explain.

主題の方法により、ナノサイズの水硬性石灰の製造が実現される。この方法の結果として、注入に好適であり、強度のある石灰が形成される。特に、原料として単一の材料を使用することは、この方法の最も重要なステップのうちの１つである。
本発明は、ナノ水硬性石灰を含むレディインジェクション材料の製造方法に関し、この製造方法は、以下のステップ：
ａ．原料として、７０％以上のＣａＣＯ３を含む泥灰土（粘土質石灰石）を選択するステップと、
ｂ．原料として４００μｍ未満の粒経を有するように選択された泥灰土（粘土質石灰石）を粉砕するステップと、
ｃ．原料として選択された泥灰土（粘土質石灰石）を焼成するステップであって、温度は１０００〜１２００℃であるステップと、
ｄ．焼成プロセス後、原料として選択された泥灰土（粘土質石灰石）を再粉砕するステップと、
ｅ．粉砕プロセス後、焼成泥灰土のｄ９０粒を４８６ｎｍまで縮小するステップと、
ｆ．粒径を縮小した材料に乾式混合処理を施すステップと、
ｇ．乾式混合プロセス後に材料に水を加え、機械的混合プロセスを８００〜１０００ｒｐｍの回転で３〜６分間適用するステップと、
ｈ．得られた材料に超流動化化学添加剤を加えるステップと、
ｉ．超音波ホモジナイザー及び機械的混合を使用して、３〜６分間材料を混合するステップと、を含むことを特徴とする。 The subject method results in the production of nano-sized hydraulic lime. The result of this method is the formation of strong lime, which is suitable for injection. In particular, using a single material as the raw material is one of the most important steps in this method.
The present invention relates to a method for producing a ready-injection material containing nano-hydraulic lime, which is described in the following steps:
a. As a raw material, a step of selecting marl (clay limestone) containing 70% or more of CaCO 3 and
b. A step of crushing marl (clay limestone) selected to have a grain size of less than 400 μm as a raw material, and
c. A step of calcining marl (clay limestone) selected as a raw material, in which the temperature is 1000 to 1200 ° C.
d. After the firing process, the step of re-grinding the marl (clay limestone) selected as the raw material, and
e. After the crushing process, the step of reducing d 90 grains of calcined marl to 486 nm,
f. A step of performing a dry mixing process on a material with a reduced particle size,
g. After the dry mixing process, water is added to the material and the mechanical mixing process is applied at a rotation of 800-1000 rpm for 3-6 minutes.
h. Steps to add superfluid chemical additives to the resulting material,
i. It comprises mixing the materials for 3-6 minutes using an ultrasonic homogenizer and mechanical mixing.

ステップａ）では、少なくとも７０％のＣａＣＯ３を含む泥灰土（粘土質石灰石）は、ＣａＣＯ３に加えて、ＳｉＯ２、Ａｌ２Ｏ３、Ｆｅ２Ｏ３及びＭｇＯの化合物も含む。 In step a), the marl (clay limestone) containing at least 70% CaCO3 also contains compounds of SiO 2 , Al 2 O 3 , Fe 2 O 3 and MgO in addition to CaCO 3.

ステップｂ）では、製品全体が４００μｍ未満の粒径を有するように粉砕される。 In step b), the entire product is pulverized so as to have a particle size of less than 400 μm.

ステップｇ）では、水／乾燥粉末の割合は、重量を基準として１．６〜１．９で変化する。このステップでは、水の添加により、流動性、体積固定性及び浸透特性が材料にもたらされる。 In step g), the water / dry powder ratio varies from 1.6 to 1.9 relative to weight. In this step, the addition of water brings fluidity, volume fixation and permeation properties to the material.

ステップｈ）では、材料に添加される超流動化化学添加剤は、ナフタレンまたはポリカルボキシレートベースの超流動化剤から選択される。 In step h), the superfluidizing chemical additive added to the material is selected from naphthalene or a polycarboxylate-based superfluidizing agent.

本発明では、ナノ水硬性石灰を含むレディインジェクション材料の製造方法の最も重要なステップは、原料の選択である。本方法のステップのうちの１つである粉砕プロセスでは、使用する材料を縮小してナノサイズにする。別の重要なステップは焼成である。焼成は、石灰製造の主要プロセスである。所望のサイズに縮小された原材料は、既知の方法を使用することにより好適な温度で焼成され、天然の水硬性石灰の製造が実現される。 In the present invention, the most important step in the method for producing a ready-injection material containing nano-hydraulic lime is the selection of raw materials. In the grinding process, which is one of the steps of the method, the material used is reduced to nano size. Another important step is firing. Baking is the main process of lime production. The raw material reduced to the desired size is calcined at a suitable temperature by using known methods to achieve the production of natural hydraulic lime.

この方法の最も重要なステップのうちの１つである注入材料の調製ステップの間、選択された量の水、化学添加剤の割合及び適用された混合手順によって、注入材料によってもたらされるべきである流動性、体積固定性及び浸透特性の制限条件が満たされる。 During the preparation step of the injectable material, which is one of the most important steps of this method, it should be brought about by the injectable material by the selected amount of water, the proportion of chemical additives and the applied mixing procedure. Restrictions on fluidity, volume fixation and permeation properties are met.
